# Which Problems Are Solved
The event execution system currently uses a projection handler that
subscribes to and processes all events for all instances. This creates a
high static cost because the system over-fetches event data, handling
many events that are not needed by most instances. This inefficiency is
also reflected in high "rows returned" metrics in the database.
# How the Problems Are Solved
Eliminate the use of a project handler. Instead, events for which
"execution targets" are defined, are directly pushed to the queue by the
eventstore. A Router is populated in the Instance object in the authz
middleware.
- By joining the execution targets to the instance, no additional
queries are needed anymore.
- As part of the instance object, execution targets are now cached as
well.
- Events are queued within the same transaction, giving transactional
guarantees on delivery.
- Uses the "insert many fast` variant of River. Multiple jobs are queued
in a single round-trip to the database.
- Fix compatibility with PostgreSQL 15
# Additional Changes
- The signing key was stored as plain-text in the river job payload in
the DB. This violated our [Secrets
Storage](https://zitadel.com/docs/concepts/architecture/secrets#secrets-storage)
principle. This change removed the field and only uses the encrypted
version of the signing key.
- Fixed the target ordering from descending to ascending.
- Some minor linter warnings on the use of `io.WriteString()`.

(cherry picked from commit a9ebc06c77)
## Which problems are solved
The execution of statements of projections did not have the context
present.
## How the problems were solved
Pass the context to the execute function
## Additional info
This change is required to use the repositories of the relational tables
in projections.
(cherry picked from commit 20e7807ee5)
# Which Problems Are Solved
We saw high CPU usage if many events were created on the database. This
was caused by the new actions which query for all event types and
aggregate types.
# How the Problems Are Solved
- the handler of action execution does not filter for aggregate and
event types.
- the index for `instance_id` and `position` is reenabled.
# Additional Changes
none
# Additional Context
none
(cherry picked from commit 60ce32ca4f)
# Which Problems Are Solved
Actions v2 is not a feature flag anymore, include functionality on
executions is not used and json tags of proto messages are handled
incorrectly.
# How the Problems Are Solved
- Remove actions from the feature flags on system and instance level
- Remove include type on executions, only in the API, later maybe in the
handling logic as well
- Use protojson in request and response handling of actions v2
# Additional Changes
- Correct integration tests for request and response handling
- Use json.RawMessage for events, so that the event payload is not
base64 encoded
- Added separate context for async webhook calls, that executions are
not cancelled when called async
# Additional Context
Related to #9759Closes#9710

(cherry picked from commit b8ba7bd5ba)
This pull request improves the scalability of the session API by
enhancing middleware tracing and refining SQL query behavior for user
authentication methods.
# Which Problems Are Solved
- Eventstore subscriptions locked each other during they wrote the
events to the event channels of the subscribers in push.
- `ListUserAuthMethodTypesRequired` query used `Bitmap heap scan` to
join the tables needed.
- The auth and oidc package triggered projections often when data were
read.
- The session API triggered the user projection each time a user was
searched to write the user check command.
# How the Problems Are Solved
- the `sync.Mutex` was replaced with `sync.RWMutex` to allow parallel
read of the map
- The query was refactored to use index scans only
- if the data should already be up-to-date `shouldTriggerBulk` is set to
false
- as the user should already exist for some time the trigger was
removed.
# Additional Changes
- refactoring of `tracing#Span.End` calls

# Which Problems Are Solved
Actions v2 are not executed in different functions, as provided by the
actions v1.
# How the Problems Are Solved
Add functionality to call actions v2 through OIDC and SAML logic to
complement tokens and SAMLResponses.
# Additional Changes
- Corrected testing for retrieved intent information
- Added testing for IDP types
- Corrected handling of context for issuer in SAML logic
# Additional Context
- Closes#7247
- Dependent on https://github.com/zitadel/saml/pull/97
- docs for migration are done in separate issue:

# Which Problems Are Solved
The action v2 messages were didn't contain anything providing security
for the sent content.
# How the Problems Are Solved
Each Target now has a SigningKey, which can also be newly generated
through the API and returned at creation and through the Get-Endpoints.
There is now a HTTP header "Zitadel-Signature", which is generated with
the SigningKey and Payload, and also contains a timestamp to check with
a tolerance if the message took to long to sent.
# Additional Changes
The functionality to create and check the signature is provided in the
pkg/actions package, and can be reused in the SDK.
# Additional Context
Closes#7924

- some renaming

# Which Problems Are Solved
The current v3alpha actions APIs don't exactly adhere to the [new
resources API
design](https://zitadel.com/docs/apis/v3#standard-resources).
# How the Problems Are Solved
- **Breaking**: The current v3alpha actions APIs are removed. This is
breaking.
- **Resource Namespace**: New v3alpha actions APIs for targets and
executions are added under the namespace /resources.
- **Feature Flag**: New v3alpha actions APIs still have to be activated
using the actions feature flag
- **Reduced Executions Overhead**: Executions are managed similar to
settings according to the new API design: an empty list of targets
basically makes an execution a Noop. So a single method, SetExecution is
enough to cover all use cases. Noop executions are not returned in
future search requests.
- **Compatibility**: The executions created with previous v3alpha APIs
are still available to be managed with the new executions API.
# Additional Changes
- Removed integration tests which test executions but rely on readable
targets. They are added again with #8169
# Additional Context
Closes#8168
